Correct gamma for mpeg2
Apologies if this has been answered before, but I couldn't find it.
First off, I'm using compressor 1.2. Can anyone tell me the right amount of gamma for mpeg2 files to use in coordination with DVD studio Pro 3?
For the past couple of years I've been using a gamma setting of 1.4 on all my mpeg2 encoded files. If it were any less the build from DVD Studio Pro looked washed out and milky. Anyways, with gamma 1.4, the build looked great on my comp and DVD player output on normal (interlaced?) setting. I recently got a progressive scan DVD player and found that the image was incredibly dark on my TV! Why is this? Thanks, hope someone can help.
Should I exort my mpeg2's with no gamma correction?
Perhaps, but not necessarily. If you have a workflow that you are happy with then there is no reason to change. What you want is a procedure where what you see in editing is what you get on your primary viewing device (but, of course, you do want some interoperability so that your movies still look good when you use a different playback device). Having a color calibrated workflow is the first big step in getting there.

Lack of support for mpeg2 is moraly wrong !
I feel it is morally wrong for this application to not support the native format of the end product.
Dvd is mpeg2 -- mpeg2 is dvd. How can you possibly sell a product that does not support the native format of the product.
I have seen comment that apple are leaving space for the pro apps. Crap !!!! there is nothing pro about mpeg2. It is a domestic standard.
bluray - dvdhd are new formats does that make them pro. NO.
I do not expect the next 'update' top include suport for mpeg2, perhaps apple cant afford the licencing ??
I am just really aggrivated that I cannot use the mpeg2 video from my camera directly in a DVD application.
Apple should be ashamed to deliver this product with this missing feature.
Cheers,
Gerrit."Morally" wrong?
Just because you chose a video camera that saves footage in an inferior format that is really meant to be the final, viewable version and not to be edited or further processed in other application, no need to get all up in a tiff that Apple is somehow to blame for your poor purchasing decision.
Part of the issue with supporting MPEG2 in iDVD is that you are missing one key point. Not all MPEG2 files are created equal. MPEG2 files can be compressed/encoded in a wide range of settings, bit rates, etc. In order to fit all your content you want onto a Video DVD, iDVD has to determine the bit rate and compression settings in order to make it all fit. It is very unlikely that some random MPEG2 file you drop into iDVD is going to have the correct compression method needed for that particular iDVD project and therefore iDVD would first have to expand the MPEG2 file back out to a standard DV video format then re-encode it back into MPEG2 at the correct settings to make it work with the rest of the DVD content. This would make for a very LONG process in an already long process and take up a TON more drive space to work.

Exporting audio and video together for Mpeg2 dvd
Hi, I'm trying to export audio and video together for Mpeg2 dvd.. I changed multiplexing to DVD but is still exporting seperately is there something im missing? thanksa
To add, with Multiplexing set to NONE, check what the Audio format is set to. If "PCM", this is an uncompressed .wav file and will result in export of .m2v video and .wav audio (I think Mac uses .aif) and use "Import as Timeline" in Encore for both clips at once. Encore will automatically transcode the audio to Dolby AC-3, do NOT mess with settings in Encore, defaults are correct. If you have CS6, then in AME audio settings, there is an option for Dolby and you can use that to create the .ac3 audio and then Encore does NOT do any transcoding to audio or video. Note that older versions will also show "Dolby" but that is a free trial of a surround encoder, not the same. You just want the stereo option available in CS6, or use PCM option is fine
Thanks

Correct gamma when using Image Adjustments Exposure?
This is a question on the gamma adjustment available in Image > Adjustments > Exposure on Photoshop CS2 for Windows.
The Gamma parameter in Image > Adjustments > Exposure seems to calculate something other than a simple gamma function (i.e. new_pixel = old_pixel ^ gamma) for the shadows.
The online help says:
"Gamma Adjusts the image gamma, using a simple power function. Negative values are mirrored around zero (that is, they remain negative but still get adjusted as if they were positive)."
Now if I create a simple 8bit greyscale gradient, then apply that function with a gamma value of 1.5 and then plot the result, I get some funny curve in the darks. If I do the same with the grey (middle) slider in the Levels dialog, I get a nice exponential function as expected after a gamma correction.
Can anyone shed some light on what is happening in Image > Adjustments > Exposure > Gamma?
Thanks a lot in advance
MartinI cannot repro that. Here's what I do:
1. Start a new document, 256x256 pixels, sRGB color space
2. Add two vertical guides to the left and the right border, so you can snap to it
3. Make a black-to-white gradient with dithering on from left to right, snapping to the guides
4. Duplicate the background layer twice, producing layer 2 and 3
5. With layer 2 active, open Image > Adjustments > Exposure and set Gamma=1.5, click OK
6. With layer 3 active, hit Ctrl+L for Levels and set the middle (grey) input levels value to 1/1.5 = 0.6667 and hit OK
7. Now turn the visibility of layer 3 on and off --> you will see a difference in the blacks, in pixel columns 60 and below; you could also use the color sampler tool to verify the pixel values are different. For example, the pixel at x=40, y=165 has RGB=1/1/1 with the exposure tool, and RGB=4/4/4 with the Levels tool.
Note: At least on my system, the difference is MUCH more visible when I use the color profile generated by an Xrite eyeone that calibrates my system to D65, gamma 2.2, 120 cd/m^2. Without the profile, the difference is barely visible.

In need of help figuring this phone stuff out! I am trying to get all the apps from my husbands old phone to his new one. I have already backed up the old phone and got everything onto iTunes, but every time I plug the new iPhone 5s into my computer it says that the version of iTunes is not correctly localized for this language and asks for me to run the English version. I have no idea how to do that? Please help.

my laptop will not open iTunes, as it just says 'This version of iTunes has not been correctly localised for this language. Please run the English version'. I have not synconised my iPhone 5S or iPad 2 with iTunes for well over a year. I noticed the music which had previously been put into iTunes has dissappeared from my phone and iPad. I also want to remove some movies from my iPad and iPhone and there is no way I can do this without being able to manually sync with the Laptop which is running windows 7. Has anyone else come across this and please can you help? I am no expert in fact I know very little about the Laptop, it is my Husbands baby but he doesn't understand anything to do with Apple including iTunes. I will need any advise explained step by step please.
Hi Shelady,
Try downloading and reinstalling the latest version of iTunes from the first link below. If that doesn't do it, the suggestions in the second article should resolve the installation issue.

Unable to create Correction Delivery for Sales Agreement
We are having the issue of not being able to create correction deliveries for ceartain Scheduling Agreements. I enter in a valid scheduling agreement number into transaction VA32, click the "JIT DlSch" button, click "Corr. Delivery" button and then enter in a date and quantity.
After I hit "Save" button, I am taken back to the initial VA32 screen and see the following message...
Sched. Agr. w/ Rel. ####### has been saved (no delivery created)
Message no. V1261
Does anybody have any insight to why this is happening? Thanks in advance.
MikeHi,
What is the Correction Delivery Type that you used? Please check in the definition of Sales Document VOV8 (Scheduling Agreement) in 'Corr. delivery type' field under 'Scheduling Agreement' section.

Stock Ledger Report in Day Wise not giving correct values for Opening Stock
Dear Experts,
I m working on Sock ledger report to give the day wise data.
since yesterdays closing Stock will become opening stock of today,
To get Opening Stock,
I have restricted the stock key figure with 2 variables on calday
(DATE FROM var with <=(Lessthan or equal to) and offset -1
DATE TO var with <=(Lessthan or equal to) and offset -1)
To get Closing Stock,
I have restricted the Stock key figure with 2 variables on calday
(DATE FROM var with <=(Lessthan or equal to)
DATE TO var with <=(Lessthan or equal to) )
But in the output Opening stock values are not coming correctly and for given range of dates,
for last date, opening stock is showing as Zero.
Could you please tell me how can I achieve the correct values for opening stock.
Thanks in advance.Hi Arjun,
Seems like you are making it more complicated. What is your selection screen criteria?
Ideally you should only use the offset.
You will have say Calday in rows and stock in Column
____________Opening Stock_____________Closing Stock
01/06/2009___(Closing stock of 31/05/2009)_(Stock of 01/06/2009)
02/06/2009___(Closing stock of 01/06/2009)_(Stock of 02/06/2009)
03/06/2009___(Closing stock of 02/06/2009)_(Stock of 03/06/2009)
So, from above scenario, create one RKFs and include Calday in it. Create a replacement path variable on calday and apply the offset as -1.
So, your Opening Stock will be calculated by closign stock of previous day.

Whenever I update my iPhone software, it asks me to sign in to iCloud with an old email address. My other devices all have the correct address. How can I get the correct address for my iPhone? The only Apple ID that works for logging in is my new one.
To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iPhone (if you're using iOS 7), then sign back in with the ID you wish to use. If you don't know the password for your old ID, or if it isn't accepted, go to https//appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Tap edit next to the primary email account, tap Edit, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device, even though it prompts you for the password for your old account ID. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

How can I create a form in FormsCentral be a self-correcting quiz for my students?
How can I create a form in FormsCentral be a self-correcting quiz for my students?
Hi;
You can't make it self correcting.
The only related idea I have is you could publish the Response Table (the "View Response" tab). You could add an entry for the "right" answers so after a student completes the form the re-direct URL could take them to the Response Table where they could see their entry along with the right answers that you had added.
They could not edit their response to correct it unless they have a FormsCentral account (free is fine) and you share the form with them, otherwise they can still view the link to see how they did (but would also see all of the other students answers).
If this sounds interesting I can give more detail on how to set it up.
Thanks,

The Calendar app that came on my i4S Phone does not sync the correct time for items posted on my Yahoo Calendar. Actually, items post exactly 4 hours earlier than the correct time on my Yahoo Calendar. My i4S is in the correct New York time zone. Help?
I posted this question a while ago and didn't receive any responses but there are a lot of people who have viewed it and 10 have said they have the same question so I thought I would update you that I added my nanny to my exchange server account (created an email for her) and I send all invites to that email address and they work. So sending invites from an exchange server account to a non-exchange server account apparently is a bug so to solve it, get on an exchange server I guess.

My iTunes will no longer download.
All of a sudden I get the message "This version of iTunes has not been correctly localized for this language. Please run the English version".
How do I fix this and run the English version again? .Start by trying to repair iTunes from the programs and features control panel.

I did a system restore, trying to get rid of the new update (which I HATE), and now when I try to open iTunes, I get an error message telling me that "This version of iTunes has not been correctly localized for this language. Please run the English version." You can't change the language option unless you can open iTunes - and IT WON'T OPEN!!! What a piece of crap! If there existed an iTunes substitute, I would purchase it in a hot minute!
Strip it out and start again.

If you really want to roll back to 11.4 uninstall all iTunes/Apple components as described in the second box, restore the pre-upgrade version of the library as described in Empty/corrupt iTunes library after upgrade/crash, then download and install from one of these direct links:
iTunes 11.4.0.18 for Windows (32-bit) - iTunesSetup.exe (2014-09-09)
